NTTED STATES PATENT OFFICE.

ROBERT A. MOOAR'IY, OF DETROIT, MICHIGAN, ASSIGNOR TO THE RAPID SERVICESTORE RAILWAY COMPANY, OF SAME PLACE.

TRACK FOR STORE-SERVICE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 378,514, dated February28, 1888.

Application filed May 1'7, 1887. Serial No. 238,501.

To aZZ whom it may concern:

Be it known that I, ROBERT A. MoCARTY, a citizen of the United States,residing at Detroit, in the county oftVayne and State of Michigan, haveinvented a new and useful Improvement in Store-Service Railway-Tracks,of which the following is a specification.

My invention consists in an improvement in tracks for store-servicerailways, which enables me to operate a car overa track in other thanstraight lines.

Figure 1 shows a plan view; Fig. 2, a side elevation of my improvedtrack, looking from a point outside of the curve; and Fig. 3 is anenlarged crosssectional view on the line x x of Fig. 1.

In operating store-service railways of the class in which a car. ispropelled by an impulse communicated to it at the commence ment of itsflight and not by an impulse continuing through the entire period of itspassage from one station to another, it is found that the greatresistance to the forward motion of the car, caused by the interpositionof a curve in the track, frequently stops the car either at thelaterally extending curve or shortly after it has passed the curve, andthat while the initial impulse may be sufficient to carry the our pastthe entire curve it is frequently not sutlicient to carry it home afterit has passed the curve. To obviate the difficulty, in cases where it isdesired or necessary to introduce a 1atera1ly-extending curve into thetrack, I place it, properly braced and tied, at the highest point in thetrack, inclining the track both ways from said curve, so that after thecar has been forced around the curve from either station it will proceedon its course to the opposite station by the force of gravity.

(No model.)

A represents a thin strip of metal. curved into the desired are to beused in the track and held out to place by the brace-rod O O 0,extending from the standard or hanger D, which either rises from thefloor or depends from the ceiling, or is the corner of a wall orobstruction around which it is desired to lead the curved track.

The curved strip A is grooved on its outer side to permit the track-wireB to sink fully or partially into it. The middle point, M, of

the curved piece A is on a higher plane than that passing through theends E E ofthe curved piece A, and from the ends E and E the trackwire Bdescends to either station. By this arrange ment, if sufficient initialimpulse is given to the car to compel it to pass the center M of thecurved piece A, sustaining the track, the car will run by gravity to theother station.

-\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. In a store-service railway-track of the class in which a car ispropelled over the track, a laterally curved supporting piece aroundwhich the track-Wire is led and from either end of which the track'wireinclines downward to a station.

2. In a store-service railway-track of the class in which a car ispropelled over the track, a track consisting of a wire strained around alaterally and vertically curved supportingpiece which is located in thecourse of said track at a point higher than is the track at either ofthe terminal stations.
